The father of missing Utah mom Susan Powell launched his own search this week after police said the case is at a standstill because they've run out of tips.
Susan's father Chuck Cox announced on the website for the nonprofit Susan Cox Powell Foundation that he was starting a search Tuesday on a 400-mile stretch of Interstate 84 from Pendleton, Ore. to Tremonton in northern Utah.
Susan Powell disappeared in 2009 and has never been found. Her husband, Josh Powell, killed their two sons and himself in February 2012. His brother Michael Powell, who was suspected of helping get rid of Susan Powell's body, killed himself a year later.
